ApplicationMay 24, 1944, Serial No.- 5875080 1 claim. (el. ihr- 297)This invention relates to improvements in lumber splicers and morespecifically, to a set of lumber splicing implements. Since the usualdimensions of lumber are not always available in all the usual lengths,it happens frequently that a builder must buy lumber which is longerthan that which he really needs. Consequently, he has to cut ou parts ofthe long pieces of lumber, and -these parts are Waste. It is moreadvantageous for the builder, and it is a matter of national interestand importance to buy short pieces of lumber, which are cheaper thanlong pieces, and to make lumber of the required length by putting shortpieces together. Therefore, the objects of my improvement are asfollows:

First, the provision of a splicer which is light in Weight, primarilyflat, and which Will form a safe connection between two pieces oflumber.

Second, to afford facilities for properly supporting and pressing towardeach other the pieces of lumber which are to be connected to each otherin such a manner that a long piece consistingof two or more short piecesof lumber, which are joined together end to end, will be perfectlystraight.

In the drawing:

Figure 1 is a side elevation of a preferred ernbodiment of a detail;

Figure 2 is a bottom plan View of the detail shown in Figure l;

Figure 3 is side elevation of a modification of the detail of Figures 1and 2.

Figure 4 is a bottom plan view of the modification shown in Figure 3.

Figure 5 is a. plan View of two pieces of lumber spliced togetheraccording to the present invention;

Figure 6 is a sectional view on the line 6 6 of Figure 5;

Figure 7 is top plan view of a complete embodiment of my invention;

Figure 8 is a side elevation embodiment of Figure 7;

Figure 9 is a sectional View on the line 9 9 of Figure 7 and Figure 10is a sectional View on the line III-I0 of Figure 7.

Similar numerals refer to similar parts throughout the several views.

The details illustrated in Figures 1 to 6 inclusive, are shown in anenlarged scale.

The ends of the lumber pieces I and 2 which are to ybe connected to eachother, are rst sawed perfectly square so that they will fit well whenthey are joined together end to end. Then, the

of the complete pieces'l andv2 are laid on a largev plank 3, to which aside panel 4 is secured by means of nails or in any other suitablemanner (Figures '7 to 10 inclusive). When the pieces I and 2 are broughttogether so that they form one absolutely straight dimension, they arerst connected to each other provisionally, preferably by means offasteners 5 (Figures 5 and 6) or the like, the fasteners 5 shown in thepresent instance forming no part of my present invention.

Each splicer consists of a piece of thin sturdy material such as sheetmetal, plastic material and the like of L-section as shown in Figures 1to 4 inclusive. One flange 6 of the L-shaped piece is just long enoughto cover the shorter side of the ends of the lumber pieces which are tobe joined together end to end, whereas the other fiange I is so longthat it-when bent around the lumber-can cover both longer sides of theends of the pieces of lumber and the second Shorter side as indicated indashand dotted lines in Figure 1. Flange 1 can also be so long thatit-when bent around the lumber-covers all four sides of the ends of thelumber pieces, as indicated in dash and dotted lines in Figure 3 and infull lines in Figure 6. According to the modification shown in Figures 3and 4, rows of perforations 8 are provided in ange 'I at those placeswhere ange 'I is to be bent around the edges of the lumber pieces I and2.

The plank 3 is provided with lengthwise adjustable means for pressingthe pieces of lumber t0- Wards one another end -to end while they arebeing joined together.

I prefer to carry out this feature of my invention in the manner shownin Figures 7 to 10 inclusive, where it will be seen that a cleat I 0 islengthwise slidable on the upper side of the left portion of plank 3 andcan be retained after adjustment by means of bolts I I and thumb screwsI2; the bolts I I are extended through the cleat I0 and throughlongitudinal slots I4 in plank 3 (Figures 7, 8, and 9). To one edge ofthe upper side of the right portion of plank 3, I secure an angle ironI5, the vertical ange of which is provided with a row of perforationsI6, and the inner side of the opposite portion of the side panel 4 isprovided with recesses preferably with ratchet teeth II as in theinstance shown; a at spring I8 having a protruding part I 9 at one endis adapted to be held between the ratchet portion of the side panel 4and the angle-iron I5, through one of the perforations I6 of which thepart I9 can be extended as shown in Figures 7, 8, and 10.

When the pieces of lumber have been joined together provisionally bymeans of the fasteners 5 as previously referred to, I place the L.shapedopen pieces on the plank 3 so that the long anges l lay'between theplank 3 and the ends of the pieces of lumber which are to be splicedtogether, as shown at the left portion of Figures 'l and 8. I adjust thecleat l0 and the resilient spring I8 in such a manner that the ends ofthe pieces of lumber are pressed towards one another. The straight topsurface of plank 3 and the side panel 4 facilitate the straightening outof the lumber y pieces. Then vI bend the L-shaped pieces around thejoined ends and secure the splices firmly to the lumber by means ofnails 20 or the like, which are driven through pre-made holes 2|intorthe lumber as may be seen at the right portion vof Figures 7 and 8and in Figures 5 and 6.

Having thus described my invention, what I claim and desire to secure byLetters Patent in the United States is:

A lumber splicing implement comprising a plank having a side panelsecured to one of its longitudinal edges, a cleat adjustable lengthwiseand attached to the top portion of said plank, a anged angular membersecured to the other longitudnal edge at one end of said plank, ksaidangular member having a row of perforations in its 'vertical flange, arow of recesses in that portion of said side panel which is opposite tosaid angular member, and a fiat spring having one end adapted to beextended through one of said perforations and its other end adaptedrtoengage an opposite recess in said panel, said plank being adapted tosupport pieces of lumber while they are being joined together end toend, and said cleat in cooperation with said spring being adapted forpressing said pieces of lumber towards one another end to end while theyare being joined by a piece of material, all substantially as described.
